. Fig.

Referring to the drawings, 1 is the smoke box of a locomotive of the Mallet type in the present instance. The lower portion 2 of the smoke box is made as an integral, casting, while the portion 3 is of` sheet metal, in the present instance secured tothe lower portion by either a lap joint as shown in Fig. 2 which may be riveted orwelded to the flange 4 of the casting 2, or a butt joint may be used,

the two parts being welded together. Theentire smoke box is joined to the boiler shell 5 Y in any suitable manner.

Made integral with the smoke box casting 2 isa bearing pad 6 which carries the weight of the forward end of the boiler and smoke box7 and this bearing pad restsl on the forward unit of the Mallet type locomotive. The detailed construction of this pad will vary with the particular design of locomotive to which the invention is applied.

At each side of the lower -cast metalsecf tion of the smoke box `is a steam pipe elbow 7 made integral with the section 2 and to which the usual steam pipes in the smoke box are attached. Connected to the outer end of each elbow 7 is a steam pipe 7a leading to the rear unit of the locomotive.'v v

The exhaust pipe elbows 8 at eachside of the smoke box are also cast integral with the cast smoke box structure. Theexhaust from the rear unit of the locomotive passes through isa'n exhaust pipe connection made integral with the smoke box casting. l In the present instance f it isa ball-and-'socket connection and iscoupledto a pipe l0a leading tothe cylinder structure of the forward section of the Malletv locomotive and delivers the exa haust steam to the forward stack.

bel connected with a pipe leading to the forpassage ll of the 1 l2 in an elbow which vis made integral with yfthe smoke box structure and is arranged to wardy feed water heater and communicates with the passage leading from theforward nozzle structures. "The forward portion `13 of the smoke box is flattened as clearly shown in Fig. 2, and is elevated so as to provide room over the running gear for an exhaust pipe and other details. n

VIt will be seen bythe above-described invention that by making the lower portion of the smoke box of a Mallet locomotive as. an integralcasting, the elbows 7, 8 and l2 and ments, whichwere heretofore made as separate parts bolted to the smoke box, are now the connection l0, and other' similar attach- Y made integral with the lsmoke box structure, Y

which not only makes a substantial structure but considerably reduces the cost ofmanufacture and maintenance.

By making the lower portion of the smoke box structure in an integral casting, the bot` tom section of the smoke box can Vbe flattened without diiic'ulty, so as to raise the front portion a sufcient distance to provide room over' the running gear for exhaust pipes and other connections. 7 -V 1.
